Design general description
1. Design subject source
Air conditioning system design is the architectural environment and equipment engineering students must master the professional skills. This project intends to let the students through design Wanda shopping center podium a zone of comfort air conditioning systems, to enable students to master the design process of the air conditioning system and skilled master the methods and techniques of computer graphics, trains the student to analyze the question and solve the practical problems of the professional engineering only independent work ability, make students get plenty of exercise.
According to teachers to provide the construction plan, combined with local meteorological data, students should master air-conditioning cooling load calculation, air conditioning systems, air handling process design, selection of main equipment, and air system, water system design. Finally, drawing the design drawings, the contents of the drawings should be able to express the design intent, the depth of the drawing should be close to the level of the construction drawing..
2. engineering survey
This is my participation in the design of air conditioning system design floor A District Wanda shopping center, shopping center is located in Xiangyang City, Hubei province. Xiangfan Wanda Plaza, with a total construction area of 60 thousand square metre, Xiangfan Wanda Plaza project is mainly residential and commercial two parts, including 10 Tung 32 storey residential building, peripheral layer 2 shops, building 2 24 storey office building, 19 storey hotel building, covers an area of 13.33 million square meters, building product 60 million square meters, Xiangfan investment and commercial supporting the most complete, the largest city complex project to date.
3. design content
According to the requirements of building properties, uses and construction units, air-conditioning system of a District Wanda shopping center podium design are as follows:
1） The load calculation of the air conditioning system for the building area of the subject (mainly air conditioning cooling load).;
2） According to the room load, room function and air conditioning system form and the construction plan choice and determine the subject selected building area air conditioning system form;
3） end load calculation and air conditioning system form choice, the next step of the construction area of the air system, water system design, including wind tube, pipe line layout, tuyere choice;
4） After the design and layout of the air pipe line in the air duct of the air duct, the hydraulic calculation is carried out.;
5）Design and layout of ventilation and smoke prevention and smoke control in the selected building area of the subject;
6）the design of the air-conditioning system, the main equipment selection;
4. design main work
By using Hongye load computing software selected regional construction all need refrigeration / heat room hot and cold load; first according to the load characteristic of the construction area of the room, such as room of the nature and purpose of by understanding and comparison of different form of air conditioning system, considering economic, environmental protection, comfortable in the various factors, determine the form of the air conditioning system in the subject construction area. In addition, the design of the room ventilation and smoke control design.
4.1. air conditioning system form
The subject of building area is Wanda shopping center podium second layer region, nature of the main room have antechamber, fire compartment, debris and the main two business mall - Gome and thousands of department stores. Access to relevant data shows that, antechamber and fire compartment and debris between is do not need to set the air conditioning system, so this design only need to consider the two largest shopping malls that Gome and thousands of department stores. According to the type of medium used by the burden of indoor load, air conditioning system can be pided into the following four forms: all air system, water system, air system water and refrigerant system. Because the building is a comprehensive shopping malls, in business hours, numerous guests, a room with a large area, person flow is large, through the advantages and disadvantages of different air conditioning systems were compared, decided to use the entire air system design of the construction area. Also to all air system further understanding, the specific choice of the mode of the air conditioning system: all air VAV air system.
